customize option/variable

customize option/variable

[aalinovi]

Thank you for the quick response Eli, but I am a bit confused.

In Mickey Petersen's book "Mastering Emacs" he says:

Hint
Apropos can sort results by relevancy. Type M-x
customize-option apropos-sort-by-scores
to customize it.

But if I do M-x customize-option which becomes customize-variable,
there is no apropos-sort-by scores variable to customize.

Thank you

Arthur

That's right, you cannot customise apropos-sort-by-scores this way, so
you have to do this in your init file. Maybe it has to do with a change
in Emacs 29.1. Mickey's book is about Emacs 28.

You can customize apropos-sort-by-scores with M-x customize-option in
Emacs 29 (and 30), but apropos.el has to be loaded for Customize to
recognize the variable.  So you can do e.g. `M-x apropos' and the `M-x
customize-option apr TAB s TAB will complete to the variable and you can
customize it.

Thank you for this hint. In fact, I was not aware that navigating in
this way to the full variable name would lead you to a different
"target" than, e.g., M-x describe-variable, or M-x customize-variable
without completing the search term by apropos.

Jürgen.

Completion with M-x describe-variable (aka C-h v) in effect searches all
Emacs Lisp libraries to find completion candidates, while
customize-variable just examines loaded libraries.  Calling M-x apropos
just loads the library (you could also use e.g. M-x load-library RET
apropos), you don't need to enter search terms to subsequently get
customize-variable to recognize options in the loaded library.

Steve,

I must say, it _is_ fascinating to see how complex Emacs has been
crafted to what is is today. I used to write my thesis back then with
NTEmacs and then, after switching to the Mac, I first used Carbon Emacs,
and then Aquamacs. Now I am on an all new Emacs 29.1, and I am only
beginning to understand how it all fits together, configuring a "Vanilla
Emacs" from scratch. When is comes to search, I did only C-s for years.
This _is_ a powerful tool indeed. I like it.

Thanks, again, for explaining this.

Regards,
Jürgen.

A simple and sincere thank you to all who took the time to respond.

It is appreciated.

customize option/variable

[aalinovi]

I am running emacs-29.1 on OpenBSD.

Anytime I type M-x customize-option, as soon as I start typing it changes from
customize-option to customize-variable.

Not knowing lisp, I would appreciate some assistance in correcting this.

Thank you

Arthur

There's no need to correct anything: an option in Emacs is also a
variable.  IOW, these two are synonyms.
